I seem to be having some issues with overclocking my laptop's 8600M GS so I can run Left 4 Dead better.
I've tried using ATITool, RivaTune, and nTune. All have failed to make my OC stick. I can however change the clock of the low power mode for the card. As soon as I load up a full screen game though it goes to high power which is set to 400mhz/400mhz.
Any ideas on what drivers I should be using or how to get this OCing to work?
